Subject: [PATCH 4/5] arm64: dts: imx95: add PCIe's msi-map and iommu-map property
Date: Tue, 28 Jan 2025 16:15:58 -0500	[thread overview]
Message-ID: <20250128211559.1582598-4-Frank.Li@nxp.com> (raw)
In-Reply-To: <20250128211559.1582598-1-Frank.Li@nxp.com>

Add PCIe's msi-map and iommu-map property because i.MX95 support smmu and
its.
